NEWPORT NEWS, Va., Aug. 01, 2024 (GLOBE NEWSWIRE) -- HII (NYSE:HII) reported second quarter 2024 revenues of $3.0 billion, up 6.8% from the second quarter of 2023, driven by growth across all segments.

Operating income in the second quarter of 2024 was $189 million and operating margin was 6.3%, compared to $156 million and 5.6%, respectively, in the second quarter of 2023. The increases were primarily driven by higher segment operating income² compared to the prior year.

Segment operating income² in the second quarter of 2024 was $203 million and segment operating margin² was 6.8%, compared to $169 million and 6.1%, respectively, in the second quarter of 2023. The increases were driven by stronger results at Mission Technologies and Newport News Shipbuilding compared to the prior year, partially offset by Ingalls Shipbuilding results.

Net earnings in the quarter were $173 million, compared to $130 million in the second quarter of 2023. Diluted earnings per share in the quarter was $4.38, compared to $3.27 in the second quarter of 2023.

Net cash used in operating activities in the quarter was $9 million and free cash flow² was negative $99 million, compared to cash provided by operating activities of $82 million and free cash flow² of $14 million in the second quarter of 2023.

New contract awards in the second quarter of 2024 were $3.1 billion, bringing total backlog to approximately $48.5 billion as of June 30, 2024.

"Mission Technologies achieved another quarter of strong performance and robust growth, which has allowed us to raise our Mission Technologies revenue guidance range for the year," said Chris Kastner, HII's president and CEO. "Our shipyards achieved critical milestones during the quarter, delivering Virginia-class submarine SSN 796 New Jersey and LPD 29 Richard M. McCool Jr. We are pleased to reiterate our full year shipbuilding guidance and see meaningful opportunities for shipbuilding operating margin² improvement in the second half of the year."¹

Ingalls Shipbuilding revenues for the second quarter of 2024 were $712 million, an increase of $48 million, or 7.2%, from the same period in 2023, primarily driven by higher volumes in amphibious assault ships and surface combatants, partially offset by lower volumes in the Legend-class National Security Cutter program.

Ingalls Shipbuilding segment operating income¹ for the second quarter of 2024 was $56 million, a decrease of $9 million from the same period in 2023. Segment operating margin¹in the second quarter of 2024 was 7.9%, compared to 9.8% in the same period last year. The decreases were primarily driven by lower risk retirement on surface combatants, partially offset by a delivery contract incentive on Richard M. McCool Jr. (LPD 29).

Segment operating margin¹in the second quarter of 2024 was 7.2% compared to 6.3% in the same period last year. The increases were primarily driven by contract adjustments, incentives and volume on the Refueling and Complex Overhaul ("RCOH") program, partially offset by lower performance on aircraft carrier construction and the Virginia-class submarine program.

Key Newport News Shipbuilding milestones for the quarter:

Delivered Virginia-class submarine New Jersey (SSN 796)

Segment operating margin %¹		*4.7*	%		1.4	%			331 bps			*4.2*	%		2.0	%			218 bps

Mission Technologies revenues for the second quarter of 2024 were $765 million, an increase of $120 million, or 18.6%, from the same period in 2023. The increase was primarily due to higher volumes in C5ISR and cyber, electronic warfare & space.

Mission Technologies segment operating income¹ for the second quarter of 2024 was $36 million, compared to $9 million in the second quarter of 2023. Segment operating margin¹ in the second quarter of 2024 was 4.7%, compared to 1.4% in the same period last year. The increases were primarily driven by the higher volumes described above, a $6 million loss in 2023 on the sale of our interest in an unconsolidated ship repair and specialty fabrication joint venture, and stronger performance in fleet sustainment.

Mission Technologies results included approximately $25 million of amortization of purchased intangible assets in the second quarter of 2024, compared to approximately $28 million in the same period last year.

Mission Technologies EBITDA margin¹in the second quarter of 2024 was 8.5%, an increase from 6.7% in the second quarter of 2023.

Key Mission Technologies milestones for the quarter:

Announced strategic executive leadership appointments to advance AUKUS goals in Australia
Announced the sale of three REMUS 100s and five REMUS 300s to the U.K. Royal Navy

These statements relate to future events or our future financial performance and involve known and unknown risks, uncertainties, and other factors that may cause our actual results, levels of activity, performance, or achievements to be materially different from any future results, levels of activity, performance, or achievements expressed or implied by these forward-looking statements. Although we believe the expectations reflected in the forward-looking statements are reasonable when made, we cannot guarantee future results, levels of activity, performance, or achievements. There are a number of important factors that could cause our actual results to differ materially from the results anticipated by our forward-looking statements, which include, but are not limited to: changes in government and customer priorities and requirements (including government budgetary constraints, shifts in defense spending, and changes in customer short-range and long-range plans); our ability to estimate our future contract costs, including cost increases due to inflation, and perform our contracts effectively; changes in procurement processes and government regulations and our ability to comply with such requirements; our ability to deliver our products and services at an affordable life cycle cost and compete within our markets; natural and environmental disasters and political instability; our ability to execute our strategic plan, including with respect to share repurchases, dividends, capital expenditures and strategic acquisitions; adverse economic conditions in the United States and globally; health epidemics, pandemics and similar outbreaks; our ability to attract, train and retain a qualified workforce; disruptions impacting global supply, including those resulting from the ongoing conflict between Russia and Ukraine and in the Middle East; changes in key estimates and assumptions regarding our pension and retiree health care costs; security threats, including cyber security threats, and related disruptions; and other risk factors discussed in our other filings with the U.S. Securities and Exchange Commission ("SEC").

Exhibit B: Non-GAAP Measures Definitions & Reconciliations

We make reference to "segment operating income," "segment operating margin," "shipbuilding revenue," "shipbuilding operating margin," "Mission Technologies EBITDA," "Mission Technologies EBITDA margin" and "free cash flow."

We internally manage our operations by reference to segment operating income and segment operating margin, which are not recognized measures under GAAP. When analyzing our operating performance, investors should use segment operating income and segment operating margin in addition to, and not as alternatives for, operating income and operating margin or any other performance measure presented in accordance with GAAP. They are measures that we use to evaluate our core operating performance. We believe that segment operating income and segment operating margin reflect additional ways of viewing aspects of our operations that, when viewed with our GAAP results, provide a more complete understanding of factors and trends affecting our business. We believe these measures are used by investors and are a useful indicator to measure our performance. Because not all companies use identical calculations, our presentation of segment operating income and segment operating margin may not be comparable to similarly titled measures of other companies.

Shipbuilding revenue, shipbuilding operating margin, Mission Technologies EBITDA and Mission Technologies EBITDA margin are not measures recognized under GAAP. They are measures that we use to evaluate our core operating performance. When analyzing our operating performance, investors should use shipbuilding revenue, shipbuilding operating margin, Mission Technologies EBITDA and Mission Technologies EBITDA margin in addition to, and not as alternatives for, operating income and operating margin or any other performance measure presented in accordance with GAAP. We believe that shipbuilding revenue, shipbuilding operating margin, Mission Technologies EBITDA and Mission Technologies EBITDA margin reflect an additional way of viewing aspects of our operations that, when viewed with our GAAP results, provide a more complete understanding of factors and trends affecting our business. We believe these measures are used by investors and are a useful indicator to measure our performance. Because not all companies use identical calculations, our presentation of shipbuilding revenue, shipbuilding operating margin, Mission Technologies EBITDA and Mission Technologies EBITDA margin may not be comparable to similarly titled measures of other companies.

Free cash flow is not a measure recognized under GAAP. Free cash flow has limitations as an analytical tool and should not be considered in isolation from, or as a substitute for net earnings as a measure of our performance or net cash provided or used by operating activities as a measure of our liquidity. We believe free cash flow is an important measure for our investors because it provides them insight into our current and period-to-period performance and our ability to generate cash from continuing operations. We also use free cash flow as a key operating metric in assessing the performance of our business and as a key performance measure in evaluating management performance and determining incentive compensation. Free cash flow may not be comparable to similarly titled measures of other companies.

In reliance upon Item 10(e)(1)(i)(B) of Regulation S-K, reconciliations of forward-looking GAAP and non-GAAP measures are not provided because of the unreasonable effort associated with providing such reconciliations due to the variability in the occurrence and the amounts of certain components of GAAP and non-GAAP measures. For the same reasons, we are unable to address the significance of the unavailable information, which could be material to future results.

Segment operating income is defined as operating income for the relevant segment(s) before the Operating FAS/CAS Adjustment and non-current state income taxes.

Segment operating margin is defined as segment operating income as a percentage of sales and service revenues.

Shipbuilding revenue is defined as the combined sales and service revenues from our Newport News Shipbuilding segment and Ingalls Shipbuilding segment.

Shipbuilding operating margin is defined as the combined segment operating income of our Newport News Shipbuilding segment and Ingalls Shipbuilding segment as a percentage of shipbuilding revenue.

Mission Technologies EBITDA is defined as Mission Technologies segment operating income before interest expense, income taxes, depreciation, and amortization.

Mission Technologies EBITDA margin is defined as Mission Technologies EBITDA as a percentage of Mission Technologies revenues.

Free cash flow is defined as net cash provided by (used in) operating activities less capital expenditures net of related grant proceeds.

Operating FAS/CAS Adjustment is defined as the difference between the service cost component of our pension and other postretirement expense determined in accordance with GAAP (FAS) and our pension and other postretirement expense under U.S. Cost Accounting Standards (CAS).

Non-current state income taxes are defined as deferred state income taxes, which reflect the change in deferred state tax assets and liabilities and the tax expense or benefit associated with changes in state uncertain tax positions in the relevant period. These amounts are recorded within operating income. Current period state income tax expense is charged to contract costs and included in cost of sales and service revenues in segment operating income.

Certain of the financial measures we present are adjusted for the Operating FAS/CAS Adjustment and non-current state income taxes to reflect the company's performance based upon the pension costs and state tax expense charged to our contracts under CAS. We use these adjusted measures as internal measures of operating performance and for performance-based compensation decisions.
